PSTH 1/4 BK SPL SCX SPEC - 3M Electronic Specialty

Product Description

3 M™PSTH tubing is a high performance,

rugged heat shrinkable tubing designed

for harsh operating conditions. T h e

tubing is made from flexible elastomeric

polyester and has a continuous operating

temperature range of -55°C (-70°F) to

150°C (302°f). PSTH is resistant to a

wide range of solvents and chemicals

including aviation fuel, diesel fuel,

lubricating oils and hydraulic fluid. 3M

PSTH tubing is specifically designed to

pass the SC-X15111C military

specification but also meets the

functional requirements of MIL-DTL-

2 3 0 5 3 / 1 6 .

Data Sheet

Typical Applications

3M PSTH tubing is primarily designed

for wire harnessing applications on

military ground vehicles. It was primarily

developed for the M-1 tank program, but

is well suited for any application where

conditions call for a high performance

heat shrink tubing, particularly where the

tubing will be exposed to petroleum

based fluids. PSTH is also an excellent

choice for heavy duty equipment and of f -

road vehicles.

Shrink Ratio

3M PSTH tubing has a 2:1 shrink ratio.

When freely recovered, the tubing will

shrink to 50% of its as-supplied internal

d i a m e t e r. The recovered wall thickness is

proportional to the degree of recovery.

Ordering Information

Order PSTH Tubing by product name,

size equivalent to the expanded inside

d i a m e t e r, package type and color. A l w a y s

order the largest size that will shink

snugly over the component to be

covered.

Example: PSTH, 3/8", black, spools.
